A Collaborative Electronic Text Annotation Platform
PACTE was originally developed by CRIM for a set of research groups, notably the Laboratoire d’ingénierie cognitive et sémantique (LiNCS) and the Centre de recherche et d'expertise Jeunes en difficulté (CCSMTL). The platform, having been developed for general use, is adaptable and can meet a broad range of needs of research communities outside the initial groups.
PACTE helps users annotate large text corpora through a web interface. To improve analysis and annotation of those corpora, bilingual linguistic, lexical and semantic analysis services are available for text annotation. The platform also includes an active learning service enabling semi-automatic annotation of text attributes by letting the user interact with a machine learning module that will identify the most significant data to annotate. This service will thus predict annotation of some text attributes that were not manually annotated. Visualization and research tools are also integrated to facilitate the researcher's work.
